Multilayer ceramic capacitors (MLCCs) based on (Bi0.95Li0.05)(V0.9Mo0.1)O4-Na2Mo2O7 (BLVMO-NMO), with εr = 39, temperature coefficient of capacitance, TCC ≈ ±0.01%, and tan δ = 0.01 at 1 MHz, are successfully fabricated by a cold-sintering process at 150 °C. Scanning electron microscopy of the MLCCs combined with EDS mapping, X-ray diffraction, and Raman spectroscopy reveals well-laminated and undistorted dielectric layers composed of BLVMO and NMO discrete phases separated by Ag internal electrodes. Prototypes show comparable properties to C0G MLCCs (TCC = ±30 ppm °C−1 from −55 to +125 °C) currently commercially fabricated at 1100 °C using CaZrO3-based dielectrics with glass sintering aids and Ni internal electrodes.
